Good idea, I didn't consider that. Various parts become cleaner if it's
unconditionally part of the request. I'll try it out.

BTW, just want to mention the the return value here is unreliable until

bisect hazard. The end result is the same though, so I didn't want to
spam the mailing list with a v2 just yet.
